Description

Technical Field

[0001] The invention relates to the technical field of fiber reinforced structural component manufacturing equipment, and in particular to a fiber reinforced structural component printing and injection molding composite manufacturing equipment. Background Art

[0002] As a high-performance composite material that has attracted much attention, fiber composite materials have broad application prospects, especially fiber-reinforced composite materials represented by carbon fiber and glass fiber have broad application prospects in the fields of aerospace, rail transportation, medical equipment, etc. However, the traditional fiber composite material molding process is complicated, often requires molds, and has a long manufacturing cycle, which greatly limits the further development and application of this type of composite material.

[0003] In recent years, the emerging three-dimensional printing (3D printing) technology has provided a new method for the integrated rapid prototyping of complex structures. However, the existing 3D printing molding process still has the problem of insufficient interlayer bonding strength, which in turn affects the overall mechanical properties of the structure. Using 3D printing technology to construct complex part geometric contours can avoid the defect of traditional manufacturing processes that require the preparation of complex molds in advance. Considering the defect of low mechanical properties of structural parts directly manufactured by existing 3D printing technology, it is an effective method to improve the mechanical properties of 3D printed structural parts by supplementing the injection molding process to fill the internal space of complex geometric contours.

[0004] In addition, although 3D printing technology can achieve clean production, waste materials such as support materials are inevitable in actual use. Sometimes due to unstable equipment, failures may occur during the printing process, and reprinting is often required to produce waste. If these waste materials can be recycled and used, it will be of positive significance for saving materials.

[0005] In view of this, the present invention combines the ability of 3D printing technology to construct complex structures with the characteristics of fast molding speed and high efficiency of the injection molding process, and proposes a printing and injection molding composite manufacturing equipment for fiber-reinforced structural parts, which provides a new process and new device for the rapid manufacturing of fiber-reinforced structural parts.
